12 Claims.

. This invention relates to refrigerating apparatus and particularly tocovers ior the openings in ice cream cabinets of the type described inmy application, Serial No. 86,586, filed February 6,1926.

One of the objects of the invention is to provide an insulating coverfor such cabinets which is stronger and more durable than thoseheretofore used.

Another object of the invention is to provide an internal reenforcingmember which may be used to strengthen existing covers.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being had to the accompanyingdrawings, wherein a preferred form of embodiment of the presentinvention is clearly shown.

In the drawings:

Fig. 1 is a vertical section of a portion of a cover embodying myinvention;

Fig. 2 is a vertical section of a reenforcing member;

Fig. 3 is a plan of the reenforcing member;

Fig. 4 is a vertical section of a portion of a p cover showing amodified manner of assembling the cover and reenforcing means;

Fig. 5 is a plan of a modied form of cover; and

Fig. 6 is a plan of a modified form of re-l enforcing member.

Referring to Fig. l, it is usual to provide an ice cream cabinet 10having an opening 11 affording access to the interior of the cabinet andto close the opening by a cover 12. This cover 12 comprises a spacingring 13 and a central spacing member 16 which are constructed ofrelatively hard, thermally non-conducting material, such as wood, rubberor nbre. These spacers are located between a bottom plate 14 and a topplate 15 which are preferably made of rustresisting metal. The plate 14is provided with a flange 14a for engaging the outer surface of thespacer 13. Insulating material 17, such as cork, is placed in thechamber formed by the spacers 13 and 16 and the top and bottom plates.All of the parts just mentioned are held in assembled relation by screw18 and a knob 19. The top plate is thus supported centrally and itsperipheral portion bears upon a gask'et 20 of any Serial No.

(Cl. 22o- 24) suitable material having a bead portion 21 received by agroove 23 provided in the upper side of the spacer 13. The gasket 20projects beyond the spacer 1,3 to provide a seal between the edge of topplate 15 and spacer 13 and is adapted to engage the top wall of thecabinet 10 to receive pressure dueto the weight of the cover which istransmitted to it by a reenforcing member about to be described. Thusthe gasket 20 seals the opening 11 of the cabinet.

' It will be understood that Fig. 1 illustrates a vertical section ofhalf of the cover as above described and that the cover is symmetricalabout the screw 18 as shown in my application Serial No. 123,897, ledJuly 21, 1926. This cover may be either round as indicated in Figs. 1 to3, or it may be rectangular, as shown -in Fig. 5. In either case, Irefer to the spacer 13 as a spacing ring or rim member to indicate amember disposed at the periphery -of the plates and open in the centerto receive insulation. This peripheral ring may thus be either round orrectangular.

In order to receive the supporting forceof the cabinet transmitted tothe lid through the gasket 20, I provide` a reenfcrcing member whichincludes a plate disposed between the top plate 15 and the spacer 13 andalso between the top plate and the gasket'20. As shown in Fig. 1 thisplate projects beyond the edge of the spacer and over the projectingportion of the gasket 20. This plate may be either round or rectangular,and may also be either a. peripheral member 30' correspending to theshape of the spacer as shown in Fig. 6 or it may be a solid plate 30'extending entirely across the surface of the cover plate 15, as shownin Figs. 2 and 3, In either event the plate is formed with a pluralityof legs 31, preferably integral with the plate, which pro'ject below itand pass through the spacer 13. These legs 31 are held in positionagainst the member 13 by the insulating material 17 of the cover. Attheir lower ends the legs are formed into feet 32 which engage the lowersurface of the spacer and thus clamp the reenforcing member to thespacer. In this manner when the lid is placed on the cabinet the entireweight of the lid and the shock of dropping it in the cabinet opening isreceived by the reenforcing member through the gasket 20. Since thereenforcing member is supported on the peripheral member close to thepoint where these 2 forces are received it acts as avery substantialsupport for the lid, relieving the coverv plate of all stress due to useof the lid.

It has been found that lids made without the reeni'orcing member yasshown in my application Serial No. 123,897, referred to above, areobjectionable because the top plate 15 springs or warps away i'rom thespacer when the lid is dropped into the opening and thus allows thegasket to escape from its confining groove 23. 'I'his is due to thefactthat the cover member is supported by the knob at a point remote fromthe application of the force. My invention provides reenforcing memberswhich can/readily be inserted in existing lids, and thus remove thisobjectionable feature. It will be understood that the sheet metal ofwhich the reenforcing member is made issumciently pliable ,to permit thebending of feet 31 into engagement with the lower surface of the spacerafter the reenorcing member Ahas been inserted in the cover.

f inet comprising in combinations. top plate, a bottom plate, a spacingring separating the plates The reenforcing member may be likewiseremoved from the cover by bending the feet 3l away from the member 13.

Where the reenforcing member is placed in the lid while the lid is beingmanufactured, I prefer to spin the inturned edge of the top plate 15over the edge of plate 30 or 30 as shown in Fig.

4. Thus the reenforcing member'when assem` .bled in the cover is ininterlocking engagement with the top plate 15 and with the rim member 13and is removable from the cover and may, if desired, also be removedfrom the top plate by bending the inturned edge thereof away from themetal of the reenforcing member.
